Since the dawn of time, mankind has struggled to understand the human mind. We've come a long way since our ancestors viewed mental illness as demonic possession or witchcraft — and performed primitive craniotomies to cure head injuries.

Today, our society recognizes that mental illness affects one in four people. And these people are our friends, siblings, children and co-workers. The prevalence of conditions such as attention-deficit hyperactivity disorder (ADHD), depression, anxiety, post-traumatic stress disorder (PTSD), bipolar disorder, schizophrenia, obsessive-compulsive disorder and autism spectrum disorder is due, in part, to growing awareness and better diagnosis.
